Sorting 2 dimension gaugues

When you have a table gauge with 2 dimensions, you can either sort by the first dimension  or the second - so either down the side or across the top. You can't do both. 

There are  many situations where this is a major problem. Like if you have a list of techs and a set of dates. Either the names are in alphabetical order or the dates are listed sequentially,  Not both.

The needs to be change.
